INSULATING AND ANTICORROSIVE PAINT AND METHOD OF MAKING Sin/E.

No Drawing.

To all to 7mm it may concern Be it known that we, CHARLES ArrLE'roN and Fonens MoRAE, both residents of the town of Surf Inlet, in the Province of Brit- 5 ish Columbia, Canada, have invented certain new and useful Improvements in Insulating and Anticorrosive Paints and Methods of Making Same, of which the following is the specification.

Our invention relates to a paint to be applied to metal and other surfaces and the process by which it is made. The objects sought and obtained by our invention are a paint covering which will be proof against nitric, sulphuric, hydrochloric and other acids, an insulating material which can be readily applied to metal surfaces which will prove a covering capable of withstanding an electrical test of two hundred volts and upwardswithout failure. I

A coating for iron and steel, which will prevent oxidation, and one which will. pand and contract with the metal to which it is applied in such a manner that it will not blister or crack.

' Our invention comprises the following ingredients pine oil, beech wood creosote and coal tar. he pine oil, of which we use 5% by weight is for the purpose of providing adhesion and drying qualities to the paint, and when the paint is used on wood surfaces, the pine oil also forms a penetrative substance.

The beechwood creosote, of which we use 20% by weight, is a rust preventive and :1 preservative.

Coal tar, of which 75% is used in our composition becomes a binder for the other two and give body to the paint.

The method we have discovered by which the several ingredients are permanently held in suspension and which is an essential part of our invention is to place the pine oil and the beech wood creosote in a tank fitted 45 with an air agitator, thoroughly mixing them together, and allowing the solution to stand for a period of about minutes until they become well assimilated, after which the coal tar is gradually added, when a chemical action is set up which causes Serial No. 558,881.

heavy fumes to be thrown oil from the mixture.

The contents are then agitated by the before mentioned air agitator for a period of about 2 hours until the chemical action is completed and the various ingredients thoroughly mixed, leaving a fluid, the several parts of which are thoroughly suspended the one within the other and which dces not solidify with reasonably cold temperatures.

We reserve the right to use the ingredients named in other proportions than those stated above.

lVhat we claim as our invention is:

1. A composition to be used as a paint consisting of the following ingredients pine oil, beech wood creosote and coal tar mixed together.

2. A composition to be used as a paint" consisting of the following ingredients, by

weight; 5% of pine oil, 20% of beech wood creosote and '75 7 of coal tar mixed together.

3. A process for producing paint consisting of thoroughly mixing pine oil and beech wood creosote together then adding coal tar to the solution and then mixing to assimilate all the ingredients.

A process for producing paint consisting of thoroughly mixing pine oil and beech wood creosote in proportions of 5% and 20% respectively, then when thoroughly mixed adding coal tar in proportion of and finally thoroughly mixing all the ingredients by agitation.

5. A process for producing paint consisting in thoroughly mining pine oil and beech wood creosote, then allowing the solution to stand for about 30 minutes until well assimilated, then adding coaltar and allowing the resulting fumes to pass off and then mixing all the ingredients by agitation.
